    BB options for Truvativ Noir (GXP)

    Are there other options out there for me? Does anyone know if the Enduro seals replacements are lighter than the standard BB from Truvativ?

    Truvativ is unique in industry

    The SRAM/Truvativ system is slightly different than other external bb's (FSA/Shimano/RF/etc). However, Enduro makes a kit to convert the bearings which includes an adapter shim for the Truvativ. They are about the same weight, but the seal drag is better and you can upgrade to ceramics. On that system, there's not much weight to be saved unless you ditch the plastic internal sleeve, but if your BB shell is open to the outside, that's risking the bearings from the poorly-sealed backside.

    Only option is the Truvativ Blackbox ceramic BB or an aftermarket upgrade from the like of Enduro. The enduro one does have stronger bearings and less drag - i recommend you purchase one of those.
